Grilled Ahi Tuna Sliders

Grilled Ahi Tuna Sliders

By Traeger Kitchen

This first-rate fish gets a quick soak in sesame oil, soy sauce, and spicy red pepper flakes to start, then basks in hardwood smoke, supercharging the marinade. Grill it up and throw it on a bun with brown sugared pineapple and creamy avocado for a fresh and hearty starter.
